TEMPORARY BINDER 0R LOOSE-SHEET HOLDER.

Specication ofLetters Patent.

Application filed September 22, 1913.

Patented Apr. ist, 19M@ Serial No. 791,181.

To all whom it may concern.'

Be it known that I, Gnonen P. IVIGG1N Ton, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvementsin Temporary Binders or Loose-Sheet I-Iolders, of which the following is a specification.

This invention relates to improvements in temporary binders or loose sheet holders.

My improvements relate particularly to the adjusting mechanism.

I have specially designed my improvements for use in temporary binders or loose sheet holders of the type in which binding strips extend between the covers, such as is shown in United States Letters Patent to Bushong, No. 851,276, issued April 23, 1907. My improvements may however, be readily adapted to binders considerably modified in general structure.

The main objects of this invention are: First, to provide in a temporary binder 0r loose sheet holder an improved adjusting mechanism, by means of which the binders may be quickly and easily adjusted to permit insertion or removal of sheets, or to lock the sheets -Within the binder. Second, to provide an improved temporary binder or loose sheet holder having these features, which may be adjusted from the outside of the cover containing the adjusting mechanism. Third, to provide in an improved temporary binder or loose sheet holder an adjusting mechanism which is simple and economical in structure and very simple and convenient in operation.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a detail outside view of a structure embodying the features of my invention with the covers extended, the outer walls of the covers and also the flexible back strip or back piece being omitted. Fig.

II is a detail cent-ral section of a complete binder on a line corresponding to line 2-2 of Fig. I with the covers closed, sheets being shown in conventional form in the binder. Fig. III is a detail section on a line correspending to line 3-3 of Fig. I, showing details of the adjusting mechanism. Fig. IV is a detail section o-n a line corresponding to line l-t of Fig. I, showing the details of the cross bar or head and its guides. Fig. V is a detail outside view corresponding to that of Fig. I of a modified structure embodying the features of my invention, the outer walls of the cover being omitted. Fig. VI is a detail section on a line corresponding to line 6 6 of Fig. V. Fig. VII is a detail outside view of another modification embodying the features of my invention, the outer walls of the covers being omitted. Fig. VIII is a detail section on a line corresponding to line 8-8 of Fig. VII.

In the drawing similar reference charae ters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing the covers are designated generally by the numerals I and 2. These covers preferably consist of rectangular frames 3 having inner walls 4L, and outer walls 5, secured thereto providing chambers within the covers.

The frames are preferably of wood and the inner and outer walls are preferably of sheet metal. Y

The outer walls are faced with a suitable binding 6 of cloth or leather, while the inner walls are faced with paper or other suitable covering as 7.

The structure illustrated is provided with clamping or binding bars S pivotally mounted on hinges S) projecting from the ends of the covers. As these clamping or binding bars form no part of my present invention they are not described with further detail herein.

The binding strips l0 extend between the covers and are connected to the cover 2 at 1l, the other ends of the binding strips are connected to the adjustable member or cross bar l2 at 13. The cross bar or cross head l2 is arranged within the chamber of the cover l to be adjusted longitudinally therein, and

'leo

is provided with guide rollers 14 engaging longitudinal slots 15 Vin the inner wall of the cover, so that the cross bar or cross head is guided in its reciprocating movement. See Fig. 1V. 'Vhen the cross bar is moved toward the inner end of the cover' 1 the bind ing strips are extended to loosen the binder, and when moved in the opposite direction they are retracted to tighten the binder upon the sheets or leaves.

The cross bar 12 is provided with a central outwardly projecting arm 1G carrying a roller 17 which engages the cam groove 18 in the cam actuating member 19, the cam groove being in the outer side or face of the member, that is, the side toward the outer wall of the cover. The cam groove is in the vform of a spiral. This cam actuating member 19 inthe structure shown in Figs. 1, 1I and Hl is a worm gear, it being provided with peripheral worm teeth 20.

The actuating member gear is journaled at 21 on the inner and outer walls of the cover. The actuating worm 22 is supported by suitable bearing brackets 23 in engagement with the teeth of the actuating member 19. The shaft of the worm 241 is extended to the edge of the cover and adapted to receive a key by means of which it may be rotated from the outside of the cover, the cover being provided with a hole 25 adapted to receive the key. By this arrangement of parts l provide a device which is self locking, that is, it remains in its adjusted position without other locking means, the worm 22 engaging the teeth of the actuating member constituting a lock and further, the spiral form of the cam, it being of comparatively low pitch, tends to keep the parts in their adjusted position.

The guides for the member 12 are preferably so arranged relative to the axis of the cam and the cam engaging part engages the cam so that the strain is radial to its axis.

In the modification shown in Fig. V the journal 2G of the adjusting member 27 has an opening 28 adapted to receive a key either at its inner or outer ends. To increase the power for tightening the binder when desired 1 provide a pinion 29 which meshes with the teeth of the adjusting member 27, the pinion being provided with a key hole 30 of the same size as the key hole 28, so that the key may be used in either place.

1n the modification shown in Figs. VII and V111 the member 31 is provided with quite an abrupt cam groove 32 which extends in the arc of a circle from a point near the journal 33 of the adjusting member to a point near its periphery. More power is re quired for operating this embodiment of my invention than that shown in Fig. I, but the actuating worm 22 provides sufficient power so that the binder may be quickly and easily adjusted. It is, as stated, more rapid in its operation than the embodiment shown in Fig. I. The form shown in Fig. V also has the advantage of being more 1apid in'its operation than that shown in Fig. I. Each form has its advantages in certain sizes of binders or binders designed for certain purposes.

1 contemplate other modifications and adaptations than that shown, but have not illustrated the same as 1 believe the embodiments shown will enable those skilled in the art to which my invention relates to adapt or embody the same as may be desired.

The flexible back piece or back strip 34:

telescopes into the covers and is connected to the cross head or adjustable member 12 of one cover and to the springs 35 in the other cover. The-action of the back strip is fully pointed out in the Bushong patent hereinbefore referred to. A
